Ryzen 3 2200G Low Performance.

ben333 · Jul 18, 2018

Hi Guys,

Just finished building a PC with just the 2200G and no graphics card. However, I have been getting lower than expected performance on 3D tasks, it seems to be the GPU that is the issue and not the CPU.

For instance; I benchmarked it on 3D Mark Firestrike and got these results: https://www.3dmark.com/3dm/27592611
All reviews and user benchmarks I have seen are not far off double my graphics score.

Any help would be greatly appreciated as I have run out of idea to as why this is happening.

Did you bump ram "Dedicated for graphics" in BIOS ? default is 64 MB and it might be an issue. Set it to 512 MB if you have 8 GB ram, 1 GB if you have 12 or 2 GB if you have more than 12 GB ram.

Rdslw :

Thanks for the suggestion, but I have already looked at that. My memory was set to 256 MB by default and changing it to 1GB had little to no affect.

In order for your GPU to work best, it needs a fast system RAM (3000MHz) and it must be a dual channel (2 sticks of same type and size). This will allow your GPU to breathe.

What's your ram config then ?

it can change a lot.

The RAM in the computer is a single 2400 MHz stick that I have running at 2800 MHz CAS 16.

Thing is though, even though my RAM is a bit slow, the overall score on the pcper page for 2400 MHz RAM is 2894, my score was 1670.

Well then I think you need second stick of ram

as it does not work in dual channel.

Rdslw :

Yeah, I think I will try to pick up another stick. Difficult though as this was a very low budget PC and RAM is far too expensive right now.
Do you think that will bring it up to ~2894 though? I have a feeling that something else is taking my score down too.

If you really want to diagnose it more, you can always just do a fresh install of windows 10, update drivers, then try 3d firemark.
This way you know nothing else is installed on the computer and will know if it is some weird back ground software.

Alternatively, you can turn off everything in "start up" which may help a bit, but doesn't stop everything running in the back ground.

I suspect its because it's not dual channel.

I've found this:

SC (single channel) vs DC (dual channel) seems to change A LOT(Almost double).
Looking at your score was a bit more than half of DC ram 2400, I would expect your result to land around 3000

Dual channel doubles memory throughput, so it is definitely an issue if you don't have 2 sticks.

ben333 · Jul 18, 2018

Ah okay, thanks for the help guys!

I will try to pick up another stick when I can.

ben333 · Jul 18, 2018

Oh, one more question. It is a bit off topic to the last one, but no temperature monitoring seems to work at all in Windows. Does anyone know why that could be?
I can see the temperature in BIOS.

ElectrO_90 · Jul 18, 2018

You haven't mentioned which Temp monitoring software you have tried.

ElectrO_90 :

MSI Afterburner, HWInfo, AMD's one and one more that I don't remember the name of.
